On January 27, 1973, the United States, the Democratic Republic of Vietnam (Communist North Vietnam), the Republic of Vietnam (democratic South Vietnam), and South Vietnam’s Provisional Revolutionary Government (which represented indigenous South Vietnamese revolutionaries, often referred to as the Viet Cong) signed the Agreement on Ending the War and Restoring Peace in Viet-Nam, informally referred to as the Paris Accords or the Paris Peace Accords. America’s longest war to that date was officially over.
